Microdon spp. (Diptera: Syrphidae)
Ants (Hymenoptera: Formicidae), despite their elaborate social organization, are plagued by a multitude of arthropods that live in their nests, from mites to members of their own family. The majority of these myrmecophilous (“ant loving”) arthropods feed upon ant brood, workers, food brought into the colony, or upon other organisms such as fungi which occur in the nest. Some of the most unusual of these myrmecophilous insects are flies of the genus Microdon (Diptera: Syrphidae). Unlike most myrmecophiles, behavioral and morphological adaptations to myrmecophily in Microdon are found only in the immature stages. Adult Microdon are typical syrphid flies that lack the usual adaptations or behavior that would integrate the fly with the habits of the ant. Instead, adult Microdonappear to associate with ants only long enough to lay eggs and will be killed and eaten by the ants if they dally too long at that task. In contrast, the slug-like larva are so highly integrated into the nest of...
